Production technique of shrinkage prevention glue-free floor made of novel combined material

Abstract

The invention provides a production technique of a shrinkage prevention glue-free floor made of a novel combined material and relates to the technical field of floors. The production technique comprises the following steps that (1) a PVC decorative surface of a PVC decorative material is prepared; (2) natural cork wood chips, rubber and assistants are fused at a high temperature and subjected to tabletting to prepare a soft base material; (3) the soft base material is soaked in liquid paste resin, scraped to be flat and then dried at a high temperature; and (4) in the manufacturing process, the soaked and dried soft base material, a PVC backing material, the PVC decorative surface and an abrasion-resisting layer are sequentially stacked into a stacked body, and then an upper graining board and a lower graining board are used for conducting hot press molding on a flat-bed press. In the using process, arching and excessive gaps caused by expansion and shrinkage can be avoided; the adsorption effect to the ground is good, no glue is needed during construction, and the floor can be adsorbed to the ground directly; any single floor can be lifted after laying, and replacement and single floor cleaning are facilitated; no glue is needed for hot press molding during manufacturing, and the product is environmentally friendly and safe; and the material is soft, the sound absorption effect is quite excellent, and the feeling of feet is good.

Description

[0001] Technical field: [0002] The invention relates to the technical field of flooring, in particular to a production process of a shrink-proof glue-free floor made of a new composite material. [0003] Background technique: [0004] Laminate flooring is one type of flooring. However, the composite floor is artificially changed the natural structure of the floor material to achieve a floor whose physical properties meet the expected requirements. Composite flooring often refers to laminate flooring, solid wood composite flooring, etc. in the market. Existing composite floors are generally laid on the ground using one or a combination of two fixed connection methods, namely lock connection and glue connection. In addition to the need to pay a large amount of foreign patent royalties for the lock floor, the glue floor is not environmentally friendly because the glue pollutes the ground, and the installation convenience of the two products is still not ideal. If the hard flo...

In addition to the need to pay a large amount of foreign patent royalties for the lock floor, the glue floor is not environmentally friendly and pollutes the ground, and the installation convenience of the two products is still not ideal

If the hard floor is installed too tightly, it is also prone to swelling and jacking
